  1. 1. Mesenchymal heterogeneity in the adult human lung

    Författare :Måns Kadefors; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lung; Extracellular matrix; Adventitia; Fibroblast; mesenchymal cell; Alveolar epithelial cell; Fibrosis; Idiopathic pulmonary fibrosis; Mass spectrometry; RNA-sequencing;

    Sammanfattning : The human lung is a complex tissue consisting of a heterogeneous mix of different structures and cells, each which a specific role that together contribute to the primary function of the organ: the gas exchange. Different mesenchymal cells populate the interstitial areas around airways and blood vessels and form the connective tissue together with the extracellular matrix. LÄS MER

  3. 2. Synchronized delivery of inspired nitric oxide : Effects on oxygenation and pulmonary tension during artificial ventilation

    Författare :Erkki Heinonen; Tim Higenbottam; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; nitric oxide; pulsed administration; pulmonary hypertension; oxygenation; equine; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Sammanfattning : Nitric oxide (NO) is a mediator of vascular smooth muscle tension that metabolises rapidly in blood. NO delivered by inhalation can therefore be used as a selective pulmonary vasodilator to relieve pulmonary hypertension or to improve oxygenation with no systemic effects. LÄS MER

    Sammanfattning : The gastrointestinal tract (GIT) regulates nutrient uptake, secretes hormones and has a crucial gut flora and enteric nervous system. Of relevance for these functions are the G protein-coupled receptors (GPCRs) and the solute carriers (SLCs). LÄS MER

  5. 4. Lithium-ion Battery Safety - Assessment by Abuse Testing, Fluoride Gas Emissions and Fire Propagation

    Författare :Carl Fredrik Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire; thermal runaway; gas emission; gas explosion; propagation; safety; abuse testing; Lithium-ion; cell case explosion; hydrogen fluoride;

    Sammanfattning : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.

  7. 5. Structural properties of the mastoid using image analysis and visualization

    Författare :Olivier Cros; Michael Gaihede; Hans Knutsson; Bernard Ars; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The mastoid, located in the temporal bone, houses an air cell system whose cells have a variation in size that can go far below current conventional clinical CT scanner resolution. Therefore, the mastoid air cell system is only partially represented in a CT scan. LÄS MER
